The Weidmuller CP-SNT 24W is a single-phase switch-mode power supply delivering stable 24 V DC at 1 A (24 W) output for industrial control and automation systems. Part of the connectPower series, this compact unit accepts universal AC input (85–265 V AC, 50/60 Hz) or DC input (120–300 V DC or 80–370 V DC), making it suitable for diverse grid conditions and auxiliary power applications. Internal protection includes a 2 A time-lag fuse, thermistor inrush current limiting, and varistor surge suppression. Output ripple remains below 2%, with tight load regulation (0.5% across 10–100% load) and input voltage regulation (0.2%). The unit bridges mains failures for 35 ms at 115 V AC and 160 ms at 230 V AC, ensuring critical circuit continuity. Efficiency reaches 78% at maximum load. Screw-terminal connections on input and output simplify installation in DIN-rail housings. Operating range spans −20 °C to +50 °C; storage extends to −40 °C to +85 °C at up to 78% humidity. Compact dimensions (90.5 mm H × 52 mm W × 62.5 mm D) and 168.6 g weight minimize footprint. Certifications include CE, CSA, cULus, and GOSTME25, with compliance to DIN EN 50178, DIN EN 60950, IEC 950, and EMC standards EN 61000-6-2/-3.
